How to access HDI Container of Cloud Foundry trial account in Python?

Hi Experts,

Need your guidence with below requrement:

Is it possible to access the HDI container of Cloud Foundry "trial" using Python application (example Flask)?

I can do it very easily using Node.js express

But with Python, i am getting issues.

I am trying to access like below:

hana = env.get_service(label='hanatrial')

conn = dbapi.connect(address=hana.credentials['host'], port=int(hana.credentials['port']), user=hana.credentials['user'], password=hana.credentials['password'], encrypt="true")

Error:

========================================

hdbcli.dbapi.Error: (-10709, 'Connection failed (RTE:[300010] Cannot create SSL context: SSL trust store cannot be found: /home/vcap/.ssl/trust.pem (zeus.hana.prod.eu-central-1.whitney.dbaas.ondemand.com:23803))')

========================================

Followed the documentation below, but looks like it is not for "trial".

https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/0a99ed7085b8447cb303c43253f2c704.html

is there any way to access HDI containers of Cloud Foundry "trial" in Python?

Many thanks in advance,

Best Regards,
Venu

    For some more background on this you can have a look as well at my recent post https://blogs.sap.com/2020/04/14/secure-connection-from-hdbsql-to-sap-hana-cloud/

    The simplest solution though would be to add `sslValidateCertificate='false',` like

    conn = dbapi.connect(
    
    address=hana.credentials['host'], 
    
    port=int(hana.credentials['port']), 
    
    user=hana.credentials['user'], 
    
    password=hana.credentials['password'], 
    
    sslValidateCertificate='false',
    
    encrypt="true"
    
    )

    Have you tried the description in Connecting Python Application to SAP HANA (XSA)?

    for resolving the mistake, I set the conecction in this mode:

    var conn_params =

    {

    serverNode: "zeus.hana.prod.us-east-1.....:port",

    encrypt: true,

    schema: "EDW_...",

    uid: "SYSTEM",

    pwd: "xxxxxx",

    sslValidateCertificate: "false"

    }

    regards
